Final answer:
To determine the amount of peanuts needed for 90 ounces of banana chips, we need to apply the original recipe's ratio of peanuts to banana chips using multiplication. The ratio is not provided in the question, but with the ratio, one could calculate the exact amount of peanuts required.
Step-by-step explanation:
The question asks us to calculate the amount of peanuts needed if we know the amount of banana chips in a trail mix, based on a given ratio. Although the original question does not provide the specific ratio, we can give a general step-by-step approach for solving such a problem.
First, we would need to know the original ratio of peanuts to banana chips in Ms. Holly's recipe. For example, if the ratio is 2:1, it means that for every 2 ounces of peanuts, there is 1 ounce of banana chips in the mix.
Next, we apply this ratio to determine how many ounces of peanuts are needed for 90 ounces of banana chips. If we use the example ratio of 2:1, we would need to multiply the amount of banana chips by 2 to get the required ounces of peanuts. Thus, 90 ounces of banana chips would require 180 ounces of peanuts.
This is a simplified explanation, as the actual ratio is needed to calculate the precise amount of peanuts. The process involves using multiplication to convert the quantities based on the ratio, just as you would convert units or ingredients in the provided references for shrimp, cheese, candy, and sandwiches.
